PREFACE
This Vehicle Standards Bulletin 5 (VSB 5) was prepared by the Australian Motor
Vehicle Certification Board to replace the version issued in November 2003
comprising two parts, VSB 5A Commercial manufacture and installation of additional
seats and VSB 5B Construction and installation of additional seats by individuals.
This VSB 5 specifies a range of design and performance requirements that apply to
replacement or additional seats in motor vehicles in order to provide protection to
occupants in the event of a crash.
The major revisions in this edition of VSB 5 include:
a) Combining the requirements of VSB 5A and VSB 5B.
b) Removing side-facing seats.
c) Introducing shoulder marking labels to indicate the range of occupants who
can use the seat based on their Shoulder heights.
d) Changing the categorisation of Category 2 and Category 3 seats to revise the
lower age ranges of occupants allowed to use the seats.
e) Introducing anti-submarining feature(s) in Category 2 and 3 seats.
f) Removing child safety harnesses due to difficulties in using them correctly and
their likelihood of their contributing to Submarining.
g) Introducing the requirement that Category 2 and 3 seats must have seat belts
that are integrated into the seat structure.

SCOPE
1.1
General
This Vehicle Standards Bulletin 5 (VSB 5) provides information for manufacturers,
suppliers and installers of Additional seats in motor vehicles to assist them in
ensuring that seats they manufacture, supply and/or install provide at least the
minimum levels of protection to their occupants required by vehicle standards. It
applies to the type of vehicles listed in Section 2.
1.2
New Vehicles
If Additional seats are fitted to a New vehicle resulting in it changing from a goods
carrying vehicle (NA or NB1 category) to a passenger carrying vehicle (MA, MB or
MC category), the modified vehicle must have an approved Second Stage
Manufacturers plate affixed.
1.3
In-service Vehicles
Additional seats fitted into In-service vehicles may be constructed and installed in
accordance with this VSB 5 as an alternative to meeting the vehicle standards
requirements under the applicable state or territory transport legislation.

SEAT CATEGORY AND SELECTION
For the purpose of this VSB 5, Additional seats are divided into three categories to
allow seats to be designed and installed for occupants of different ages:
Category 1 - Seats intended for use by adults and which can be used to
accommodate a Child restraint.
Category 2 - Seats suitable for children approximately 4 to 12 years of age and
which may be used to accommodate a Child restraint depending
on the type and size of the Child restraint.
Category 3 - Seats suitable for children approximately 4 to 7 years of age and
which cannot be used to accommodate a Child restraint.
Category 1 seats must comply with the version of ADR 3/--, ADR 4/-- and ADR 5/-that applies to the vehicle. Additionally, they may be required to comply with a
version of ADR 34/-- that applies to the vehicle.
Note:
A vehicle can no longer be classified as a goods carrying vehicle if the combined occupant
mass (based on 68kg per occupant) is equal to, or exceeds, 50% of the vehicle’s payload
(the difference between the vehicle’s GVM and its ‘Unladen Mass’).
All Additional seats intended for use in front seating positions must comply with all
the applicable ADRs.

SEAT LOCATION REQUIREMENTS
6.1 General
Careful consideration must be given to the suitability of the vehicle before Additional
seat(s) are installed. If the answer to any of the questions listed in Table 2 is ‘No’, the
modification should not be carried out.
Table 2. Suitability of vehicle
Suitability of vehicle
Yes No
Is the space available in the vehicle sufficient to accommodate the Additional
seats and occupants? Specifications for the space required for Additional
seats and occupants are set out in Figures 3 and 4;
Y
N
Is access and egress from all seats sufficient to allow a person to enter and
exit the vehicle, operate door latches, folding seat controls without difficulty
or hindrance?
Y
N
Will access to seats installed in a vehicle's load space remain un-obstructed
by any load being carried?
Y
N
If an existing seat is modified to improve access, e.g. by installing a folding
mechanism, is evidence provided to demonstrate that the modified seat
complies with the relevant version of ADR 3/--?
Y
N
Are fittings, including seat backs, padded to prevent injury if they intrude into
the head space shown in Figure 3?
Y
N
Are the Additional seats, head restraints (if fitted), and their occupants
located so as to not adversely affect the driver’s rearward visibility?
Additional external rear vision mirrors may be required if rearward vision is
impaired.
Y
N
Additional seats should not be installed in the vehicle where there is a high
probability that occupants will be injured in a crash − for example there is a high
probability that an occupant in a rear facing seat in the rear of a small station wagon
would suffer leg injuries in a rear end collision, because the occupant's legs are
located in an area that will crumple as a result of the impact forces.
Additional seats shall not impose any loads on existing seats, unless it is
demonstrated that the original seats can carry the additional loads
6.2 Interference with Existing Safety Equipment
The Additional seats, relocated spare wheels and their associated equipment, shall
not prevent or restrict the use of existing safety devices such as seat belts and Child
restraint anchorages, unless alternatives that comply with all the applicable ADRs are
provided.
Note:
Child restraint anchorages are designed to withstand only those loads imposed by correctly
fitted child restraints.
Issue 3.0 Revision 1.0
Page 7 of 24
28 March 2017
6.3 Relocation of Spare Wheel
If Additional seats are to be installed in the spare wheel well of the vehicle, the spare
wheel may need to be relocated. When relocating the spare wheel, its mounting must
be of sufficient strength to withstand a deceleration of 20 times the weight of the
spare wheel and its mounting in the forward, rearward or sideways direction.
The spare wheel and its mounting must not cause a hazardous projection for the
vehicle's occupants.
6.4
Installation Kit
Seats supplied for installation by others shall include an installation kit which contains
the following:
•
Installation Instructions
Comprehensive and easily understood installation instructions which cover the
make and model of vehicle that the seat is intended to fit. The installation
instructions must be such that when correctly followed, the seat installation will
comply with all the requirements of this VSB 5. The instructions must be in
English and supporting diagrams must use SI Units.
•
Installation Hardware
Installation hardware such as bolts, nuts, lock washers, spacers and backing
plates sufficient to allow the seat, seat belts, and all necessary components to
be installed correctly.
•
Seat Label
The seat label or plate as required by the Section 8 ‘LABELLING AND
MARKING OF SEATS’.

SEAT CONSTRUCTION
7.1 General
Seat frames must be constructed so that there are no sharp edges or projections
likely to cause injury to occupants.
7.2 Seat Dimensions
The minimum effective cushion width (W) and the maximum cushion depth (D) for
each seating position must be at least that shown in Figure 1 and Table 3.
Issue 3.0 Revision 1.0

The effective cushion width is measured as per the one determined below:
•
The effective cushion width is the width of the seat cushion measured
horizontally at the intersection of the seat cushion with the transverse plane
through the Torso Reference Line.
•
The effective cushion width is determined by an analysis of seat, seat back
and vehicle structure sections on the transverse plane:
o
if a cushion is separated from another cushion by less than 100 mm the
two cushions must be regarded as continuous; and
o
if an end of the cushion is separated from adjoining structure by less
than 100 mm it must be regarded as extending to the adjoining
structure.
7.3 Space Requirements
The head space and leg space requirements specified below shall apply to each
seating position and, if the seat is adjustable, must be maintained throughout the
range of seat travel or adjustment.
The template shown in Figure 2 should be used to assist in determining compliance
with these requirements.
With reference to Figure 3, position the template on the seat’s centreline with the
Point D contacting the seat back.
